  Log Message:
  -----------
  [HLSL][SPIRV] Add -fspv-use-unknown-image-format option (#155664)

This option allows users to control the image format used for HLSL
resources
when targeting SPIR-V. When the option is enabled, the unknown image
format
is used. Otherwise, the image format is guessed based on the input type.
